Oil cooler line failure: while driving on a state route in a rural area my oil cooler line ruptured in my 2009 toyota sienna, resulting in major loss of engine oil, thus being stranded in a rural area and requiring a tow. the metal oil line was constructed with a section of rubber in the middle which deteriorates and fails. toyota has been aware of this issue for years, and first changed the rubber composition in a replacement part but this part still had a significant failure rate. so the current replacement is all metal line. why would you have a rubber section in an oil line? obviously the first two designed parts were a very poor design. toyota issued an extended warranty for siennas for 10 years and 150,000 miles but this has since expired. i was never notified of the extended warranty. why expire a warranty if the vehicle is still within the parameters of the warranty (10 years or 150,000 miles)? toyota says this is not a safety issue. but as a retired corporate safety manager/engineer with a major tire manufacturer i disagree. there ...
Car had unexplained acceleration. car had solenoid recall repair. car would surge forward slightly until accident caused it to go out of control. also, takata recall. car was filled with air bag material and side air bags caused almost fatal injury to my wife and severe injury to my son. car was traveling on side street traveling around 30 miles per hour until it sped up to 68.4 mph..
The car accelerated to 68.4 mph. i could not stop car first time with abs brakes. i took my foot off the brake and it helped but it was too late. the car hit the tree. the sienna's brakes did not work properly at first, the car so how went from 30 mph to 68.4 mph and the steering did not work. something has to be done when 1.2 million dollars of damage to a family. luckily metropolitan and aetna limited the health care personals. the car was damaged beyond repair. we have new friends called collections companies. please do not buy toyota. the corporation considers the accident not their fault.
Our 2009 sienna may have had a sudden acceleration problem. when the car was put into reverse, a sudden acceleration sent it down our driveway. situation: pulling into the carport, which involves a 90 degree turn at the top of a short (10m) steep narrow walled easement, the driver of the sienna could not make the turn in one motion and was required to put the sienna in reverse at which time the minivan suddenly accelerated, squealing its wheels. the result was a 5m careen down the driveway. the result was about $4,000 body damage, but no injury to the driver or my 2yr old daughter - although all were shaken. we have since got rid of the car - traded it for a 2010 highlander. *tr
